a similar attempt on RoboSats exploiting its collaborative-cancel feature. Has anyone else encountered something similar?
I don't know if I've heard this before but I never heard any exploit happening using Robosats even I do research to any SERP; it's a P2P exchange with no KYC but mainly uses Lightning because it has an advantage when it comes to instant sending.
I don't know if scammers have way to scam people using this platform since it's peer-to-peer encrypted with escrow. How can scammers attempt to scam someone using RoboSats? Unless this exploit you mean is actually exists, even escrow can't avoid this, then how will people trust RoBoSats?
For now, honestly, it's impossible; I've never heard that exploit.
